Pins fem analysis

Hi everybody,
I am a mechanical engineering student and I’m doing a project for a skid steer loader. In particular I am studying the structural analysis of arm in the severe operative conditions. This analysis includes, in addition to the arm, bucket (where is apply the force) and two other bodies with which the arm is connected to the frame. To define the connection between the bodies I decided to make the hinges by contact with the pins. This contact has been achieved using the contact surface type slide. The analysis target is to determine the resistance of arm and pins. 
Said this I would like to know I can optimize that analysis? Especially how can I improve the analysis on the pins? 
Thanks in advance for the help.
